Massive anti-Israel protest underway in London

Thousands of protesters took to the streets of London Saturday to call for an end to the IDF's operation in Gaza.

At least 15,000 people were expected to take part in the demonstration, which began at the Prime Minister's residence at 10 Downing Street and continued on to the Israeli Embassy in Kensington, the Guardian reported.

Pro-Palestine supporters carried posters with the messages "Gaza, stop the massacre" and "stop Israel's war crimes", according to the Guardian.
